Force Direction Tension Elastic Force Gravity Normal Force

Force Direction Tension Elastic Force Gravity Normal Force Friction Drag 1

Force Direction Tension The magnitude of the tension is the same everywhere in the rope. 2

Force Direction Name of Force Tension Symbol 3 When does this force occur? If an object that is experiencing the force is pulling but not stretching another object Where does this force occur? On the object that is experiencing the force at the point where the pulling occurs Magnitude Determined using Newton’s Second Law Direction Toward the center of the object being pulled (rope, wire, etc. ) Associated Energy No associated energy

Force Direction Spring Force 4

Force Direction Name of Force Spring Force Symbol When does this force occur? If an object that is experiencing the force is stretching (or compressing) another object Where does this force occur? On the object experiencing the force where it connects to the object that stretches/compresses Magnitude 5 Direction Toward the center of the object that stretches or away from the center of the object that compresses Associated Energy Elastic Potential Energy

Force Direction Gravity 6

Force Direction Name of Force Gravity Symbol or When does this force occur? If there are two massive objects present Where does this force occur? At the center-of-mass of the object receiving the force Magnitude 7 or Direction Toward the center of mass of the other massive object Associated Energy Gravitational Potential Energy
